To n25 who" i3 may concern:

Be it known that I, BENJAMIN it. Barnes,

a eitizen ofthe United States, residing at Le Roy, in the county of Cofiiey and State of Kansas, have invented anew and useful Oil-Burner, of which the following is a specification.

This invention relates to burners for oil or other liquid-fuel, and has for its object to provide an improved burner of this charactor for producing a maximum heating eiiect' and which shall have a smokeless flame and'novel means whereby the flame generates the liquid fuel into a vapor for combustion.

This invention also contemplates the provision of a burner of this character which is durable, simple and inexpensive in construction. 1 I V Tot-he above and other ends, this invention is-characterizedby the novel construc tion and combination of parts elicited in the following, description and pointed out in the appended-claims, reference beinghad to the accompanying drawings, wherein the invention is illustrated in its preferred embod1- ment, and wherein:.

figure 1. is an elevation of the burner, parts broken away. Fig. 2 is a sectionon Fig. 3 is a section on the line 3 3 of Fig. 1. Referring specifically to the drawings, wherein similar reference characters indicate similar parts, the burner embodies primarily a sinuous pipe designated gener-,

ally by the numeral 3, the said pipe being bent'from a length of gas pipe or the like to form therespective vertically arranged "'arallel horizontal portions 6, 8 and 10.

he upper portion 6 is connected to the intermediate portion 8 by the bend 7 and the said portion 6 is adapted to peceive the liq-' uidfuel, the portion (Fleeing connected to the 'valve 5, which val e inlurn is connected t'o'a supply-pipe 4 leading to the supply tank (not shown). The intermediate por-' tion 8 is connected to the lowermost portion 1Q by the.bend 9, and the lowermost portion 10 is provided with a pair of upper vapor outlets 12, facing the parallel portions 8 and- 6. The lower end of the pipe3 is closed by means of a cap 11 screw-threaded thereon.

A drip pan 21- is suspended or hung from the burner by means of upstandingloops 20 securcd tlo the drip pan and engaging. the lowermost portion 10. A pair of down drafttubes 14 extend fr m the intermediate portion 8 of the pipe 3 to the lowermost portion 10 and are arranged. adjacent, or to one side of the respective vapor outlets-12 and intermediate the said outlets. These down draft tubes 1d are provided with seats or notches 15 in their upper ends, the intermediate portion 8 resting or seating in the said notches or seats, and at their lower ends the tubes 14 are provided with transverse openings 19 through which the portion 10 of the pipe 3 passes. The tubes 14 have an internal diameter larger than the external diameter of the pipe 3, thus permitting or providing for a passage through the tubes 14 from "theintermediate portion 8 to the lower ends of the tubes 14 belowthe por tion 10. The lower ends of the tubes let are arranged slightly above the drip pan 21. A rod 16 passes through the upper portions 6 and 8 of the pipe 3 and through the bend 7 connecting the said portions, this rod being preferably inserted into the pipe before the same is bent and being bent with the pipe.

Upon the intermediate portion 8 of the pipe mediate portionof the concaved side there of. The portion 6 of the pipe 3 passes through the strap 18 of the spreaders or deflectors 17, thereby permitting the spreaders or deflectors to be rotated about the axis of the portion 6 and permitting the said Spreaders or deflectors to he slid longitudinally upon the portion 6.

In application, the upper portions 6 and 8 of the pipe 3 form vapor-generating chambersreceiving the liquid fuel and the said portions lie in the path of the flames issuing from the vapor outlets 12 whereby the liquid fuel is successively. raised in temperature as it passes tl'irough" the pipe, the fuel becoming first heated in'the portion 6 and then passing into the portion 8 ti) be superheated. From the portion 8, the vaporized fuel passes into the lowermost portion. 10

of the pipe 3, which portion 10 forms a tion of the vapor.

vapor chamber, and the vaporized fuel thenissues through the vapor outlets 12 and upon being ignited serves to provide the flames. The rod 16 passing through the vapongencrating chamber reduces the area of the said .Will serve to separate the two flames-and tense heat.

prevent one flame from materially affecting the action of the other flame. The drip pan 21 serves to catch any escaping or overflowing oil, and may be used for starting the burners by allowing a small quantity of oil to drip into same and then igniting the oil to heat the burner, which will provide for an initial generation of the vapor. -Upon the burner being brought into operation, the flames striking the portions 6 and 8 of the pipe 3 will heat the said portions to generate the liquid fuel into a vapor. The portion 8' of the pipe 3 has been provided .with the protectors 13 for preventing the direct contact of the flames with the said portion, thereby prolonging the life of the said burner, and the spreaders or deflectors 17 may be suitably adjusted to properly spread or deflect the flame to one side or the other. 1 This burner is durable, simple and inexpensive in construction and produces a maximum heating effect with a minimum amount. of fuel. This burner may be also used for other liquid fuel than oil and the flames provided by the burner give an in- This' device is also susceptible of alteration and deviations in its details within the scope of the appended claims without departing from the spirit of the invention.

An escape pipe 22 is also connected to the drip pan 21, which is for the purpose of carrying oil any overflow of the fuel thereby preventing the drip panbecoming full of fuel and thus dispensing with the liability generating chambers receiving the fuel, and a down draft tube extendlng from an intermediate portion of the pipebelow the lowermost portion, the lowermost port-ion passing. through the down draft tube with the vapor outlet disposed .at one side of the down draft tube. i
